An experimental optical physicist who coauthored a bright source of polarization-entangled photon pairs in 1995. Noncollinear type-II spontaneous parametric down-conversion generated the pairs, while compensation of distinguishability allowed strong polarization entanglement. A source of this kind supplies repeatable inputs for Bell tests and experiments in quantum information.[ref]
New High-Intensity Source of Polarization-Entangled Photon Pairs by Paul G. Kwiat and others. Abstract and apparatus: type-II phase matching, compensation and polarization coincidences
